Yes, I did use -msingle-pic-base -- actually, I am the one who submitted the patch for ARM to that effect, precisely after all my tests :) -- but the code growth I am talking about is accesses, not setup. >> This simply implies that -fPIC is a better choice for PPC (and hence >> -mrelocatable) while -fpie is a better one for ARM. > > -fPIC isn't optimal(it is bigger) but until my gcc patch gets into > gcc one cannot use -fpic(it gets promoted to -fPIC by gcc). > -fpic is smaller but one cannot build apps has has a GOT over 32KB with > that You get a GOT over 32 KiB? IIRC, the reloc tables for ARM with -pie are slightly below 19 KiB for a typical u-boot; I'm surprised that a GOT would go bigger than the ELF table for the same work.
